From what I've read, it looks like it has adapters for SL2 and SL100. It also looks like it breaks out the connectors on the bottom of the radio to a standard DIN connector and a standard SMB connector that would allow a connection to a standard antenna SMB adapter.

The manual comes with the Pin-outs to the DIN connector.

The ones that interest me are the Serial connectors and the Power Enable ones.

I wonder if the Power Enable is the switch to allow the antenna to work in portable mode such as the antenna headphones use?

Is there a set of standard commands that you could send the radio to do things like "Change Channels" Volume Up etc. It would be neat to connect a line analyzer in between some of the aftermarket radios which use this connector and see what they are sending back and forth to the radio.

Does anyone know if there is a technical or programmers manual for this device?

Somewhere I remember reading about interfaces to direct Connect adapters. I think someone made a computer interface once for some other radio.

Maybe TSS Taylor or Sirius Rich might have more info on this?

I don't know if it is worth 60 bucks to play with now, but it certainly looks like it might be fun. I can see lots of possibilities connecting your computer directly to your stiletto. Controlling it via the serial connection. I'm sure this is how the dock's control the stiletto turning it on, controlling the volume etc.

I sent an email to Crutchfield and they said they had no information on it. They sent me to Directed.

Directed forwarded the message to someone in Canada who said he had no information on the device. He suggested I go directly to Sirius.

No word from Sirius.

Is the serial protocol to this device a trade secret?
Obviously all the radio manufactures have commands they send to the device to change channels, adjust the volume, read the name of the songs etc. Is there some standard protocol that all the device manufacturers use? No ones talking and google is not giving me any details.

This is starting to smell like the RIAA might be involved here. I guess with a computer connected directly to radio, you could easily set up your watch list and record all those songs you are looking for.

Can one of you explain in non tech language what this thing is and why I might want it?

First off, you probably do not want it. If you have a car dock and/or a home dock that enables you to listen to your radio in the car or at home you are fine.

What this device does is allow other devices such as your car radio or home stereo to control your Stiletto.

This device along with an interface device for your car radio or home receiver will give a car radio or Home stereo receivers the ability to directly play Sirius music channels and show on their own displays the current channel and song artist etc. ie. one radio with one display.

You already get all of this information in a easy to view way from your stiletto display. ( Now I hope this is not too technical )This device allows other devices to send and receive messages that do things like turn on/off the stiletto. Turn the volume up/down. Change the channel. Get Song/artist information. This then can be displayed or acted upon on your car radio or home stereo receiver.

This is no different than having your car radio control your ipod. It just is controlling your Stiletto. The issue is that in reality most car radio's have less room to display the song information. They have fewer buttons to make it easy to change channels and perform the functions necessary to navigate in the Sirius world.

I find, it not worth the $130 dollars to buy both this cable and the necessary interface box to the car radios, only to get less functionality and display features. Additionally it makes for a more complex solution with more connectors and more failure points.

The one area where I think it might be worth it is to build a computer interface. Having a computer being able to control your stiletto might be intriging. A web interface that might be able to allow your radio to scan all the channels to look for specific songs. Once the song is found start recording it. Having remote access through the WWW might also be possible controling your stiletto via something like a slingbox. I've been searching and have posted questions on other forums who have information about the Sirius Connect protocol. Still I am really not getting much in the way of any specific answers. There are a few programs that have interfaces to other older radios. All seem to be demo not full functionality programs.

In my younger years, I wrote software for very complex PLC controllers so I probably could do something with this if I was put to the challenge. I understand that the protocol is not a simple protocol like a modem AT command set but more like a ACK NAQ where error commands and responses are expected within a few milliseconds. Kind of sounds like the old Allen-Bradley PLC protocol. But I'm getting technical and you wanted a simple answer.

Hope this answers some of your questions. Perhaps I'll get some more information if so we might see some possibilities.

No, it's not too technical at all. The initial posts were just tossing around acronyms I didn't know.

Do you know if this device would let you use stiletto functionality through say your car receivers controls? Could I play songs off of the micro sd card with those controls?

I really see no use for this device whatsoever. It would mean paying more for something than a direct connect receiver to get the same results.

The purpose is to allow you to control the stiletto through your car receivers controls. The issues are, there is a lot more to control. I guess if your receiver extends the controls to the steering wheel that might be nice.

I would assume that if it can play songs from the library then it should be able to play them from the microsd card as in our stiletto interface there really is no difference.

Since I have not seen the scope or set of commands that the sirius connect has at its disposal, I would not know what it can actually control.

Mitch over at the www.rush2112.net was most helpful. From his comments he told me All I needed was the Sirius Connect Universal Home Dock (SC-HC1)USB Interface Cable.

So I ordered this cable along with the SVCDOC1. Mitch says his demo programs probably will work to be able to connect directly from my PC to my stiletto.

I'll give his demo program a try to see exactly what it can control of the stiletto.

At the same time I can try to see if I can capture the protocol that goes between the two.

It really seems that everyone wants to keep the Sirius Connect commands "Top Secret", I've been going in circles with calls into Sirius, Directed Electronics, Crutchfield. All saying they "Know Nothing"

You know, if I get my way and figure this thing out, I'll make sure I publish a paper of some kind documenting what I find out. With a lot of new car PC's coming out in the future, this may be the unit that will bridge the two. Having my pc being able to control the stiletto would be key.

Hopefully I'll get both this week and be able to try some things out next weekend. This project at the surface, looks like it could be a bust and a waste of a hundred bucks, but hopfully I'll get something out of it. If nothing more, some more practice with my coding skills. The last time I worked with my .net development kit was when we did all the coding for the s50 with the bitmaps.

Well, we shall see... Stay tuned to this thread for further infomation.
